Application filed September 22, 1900. Serial No. 30,823. (No model.)

To (066 w/mm/ it may concern.-

Be it known that I, JOHN J. KOGER, acitizcn of the United States,residing at Homesburg, in the county of Hawkins and State of Tennessee,have invented certain new and use ful Improvements in Tell-DrillingMachines; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the characters of reference markedthereon,which form a part of this specification.

This invention relates to certain new and useful improvements in welldrilling inachines; and it has for one object the provision of simple,inexpensive, durable, and efficient machinery of this character whichwill be cheap of construction and positive in its operation.

The invention has for its essential object the provision ofawell-drilling machine adapted to be operated by horse-power and so constructed as to provide the greatest possible number -of downstrokes ofthe drill within a specified period of time.

The invention has for a further object th provision of simple andefficient means for regulating or for paying out the rope or cableconnected with the drill.

To these ends and to such others as the invention may pertain, the sameconsists in the novel construction and in the peculiar arrangement,combination, and adaptation of parts, as will be hereinafter more fullydescribed and then specifically defined in the appended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the characters of reference marked thereon, form part ofthis application, and in which drawings similar characters of referenceindicate like parts throughout the several Views,in which- Figure 1 is aperspective view of a welldrilling machine constructed in accordancewith my invention. Fig. 2 is an enlarged plan view of a portion of theoperating-wheel and its connections, showing the extreme positions ofthe operating-lever; and Fig. 3 is a sectional detail taken upon line 33 of Fig. 2.

Reference now being had to the details of the drawings by letter,Arepresents the framework or timbers designed to rest upon the ground orupon a suitable platform or level surface. This framework A issubstantially rectangular in form and is provided witha brace-timber A,extending longitudinally across the center of the frame. Atthe forwardend of the timber A an upright timber B is provided, the upper end ofwhich timber 13 is secured between the inclined timbers B, the lowerends of which timbers B are bolted or otherwise secured to the rearportion of the frame A, and at their upper ends the said timbershavejournaled between them a pulley C. At a point one-third of thelength of the inclined timbers B a fric tional pulley C is provided.

D is a capstan or drum the shaft of which is journaled within the upperends of the uprights E, rising from the outer sides of the frame A, thesaid shaft being provided with a suitable operating-handle D. A suitablepulley F is journaled at the rear end of the brace-timber A of theframe.-

G is the drill, and G the rope connected therewith.

H is a frame constructed of heavy timber and is designed to rest eitherupon a platform or other suitable level surface. Suitably journaled atthe center of the frame H is the operating-wheel I. This operating-wheelis of skeleton form, the arms I of the wheel being securely bolted attheir inner ends to the hub l and at their outer ends are connected bythe brace-timbers I A suitable arm or extension I is connected with oneof the spokes of the wheel, and at the outer end of this extended arm Iis carried a whiffletree 1 to which the horse ma; be attached. In thepresent instance I have shown an operating-wheel having eight arms orspokes, and I prefer this number of spokes, though it is at once evidentthat the number of spokes in the wheel may be varied and a greater orless number employed, if desired. K is a pitmanbar pivoted at a point ator near its inner end to a cross-timber L of the frame H, and at a pointintermediate of its ends the said pitman-bar has connected to it a ropeL, to which the end of the rope G, attached to the drill G, isconnected. Attached to the under surface of each of the spoke-timbers I,at a point adjacent to the outer ends of said spokes, is a block M,beveled upon its inner edge, as shown, these blocks M being adapted tobe struck or engaged by an idle pulley or upward extension M upon theupper surface of the outer end of the pitman-bar M, as shown, as theoperating-wheel I rotates.

N is a spring which receives the forward throw of the pitmanbar, andthus serves to relieve the jolt or jar which would otherwise be impartedto the frame.

0 is a guard, preferably of metal, which is provided at the end of theframe H above the outer or movable end of the pitman-bar. The forwardend of the said guard O is inclined upward, as shown at O, the office ofsaid guard being to insure the outer circumference of the wheel beingheld down in its movements, thus insuring the contact between the blockM and the block or frictionpulley M.

From the foregoing description it will be seen that the rope G, which isattached to the drill, is passed upward over the pulley O, thenceextended downward around the movable pulley P, and thence over thefriction-pulley G to the drum D, around which it is wound by thecrank-lever D. A rope 2 is attached to the pulley-block of the pulley Pand extended downward around the pulley F and is attached at its end tothe link or rod L, the opposite end of which rod is pivotally attachedto the pitman-bar, as described.

The operation of the machine is simple and will from the foregoingdescription be read ily understood. It will be noted that each of theblocks M, carried at the outer ends of the spoke-timbers of theoperating-wheel, in turn engage the block or friction-pulley at theouter end of the pitman-bar, and that as the wheel rotates the outer endof the pitman-bar will be carried back until the distance from thecenter of the operating-wheel to the block M is greater than the lengthof the pitman-bar, when in the furtherrotation of the wheel the pitmanwill be released and will be drawn back by the drill, thus imparting adownward stroke to the drill. The pitman in its forward movement willcontact with the spring N, thus relieving the machine from jolt or jar.The pulley M, carried upon the next succeeding spoke, will in turnengage the friction-pulley or block upon the outer I claim to be new,and desire to secure by Letters Patent, is-

1. In a well-drilling machine, the combination with the upright havingpulleys mounted thereon, a drill, a Windlass and rope connectionsbetween the latter and said drill, a horizontallydisposed wheel havingradiating spokes,a pivoted bar and connections between same and saiddrill-actuating rope, blocks on the under surface of each spoke of saidwheel adjacent to their outer ends, and an antifriction-roller mountedon the free end of said pivoted bar, and disposed in the path of saidblocks, and adapted to throw said lever as each spoke passes saidantifriction-roller, whereby the drill is raised, and means for holdingsaid wheel against vertical movement while the drill is being raised, asset forth.

2. In a well-drilling apparatus, the combination with the drill, theupright having pulleyblocks, the Windlass and rope connections betweenthe Windlass, pulley-blocks and drill, a horizontally-rotatable wheelhaving radiating spokes, blocks mounted on the under surface of eachspoke adjacent to their outer ends, a horizontally disposed guard piecehaving an upturned end, underneath which guard the projecting ends ofthe spokes are adapted to pass, a bar pivoted at one end to the frame ofthe machine, connections between said bar and the drill-actuatingconnections, an antifriction-roller at the free end of said pivoted bar,which roller is disposed in the path of said blocks, and adapted to bestruck thereby, as each block contacts with said antifriction-roller,whereby the drill is raised, substantially as shown and described. In awell-drilling machine, an upright, pulleys mounted thereon, a drill, aWindlass and rope connections with said drill and windlass, ahorizontally-rotatable Wheel having radiating spokes, blocks on theunder faces of each of said spokes adjacent to their outer ends, a barpivoted at one end to the frame of the apparatus, connections betweensaid bar and the drill-actuating ropes, horizontally-disposedcross-pieces having curved ends between which cross-pieces said pivotedI bar is guided, an antifriction-roller carried at the outer end of thepivoted bar, and disposed in the path of said blocks, a spring, againstwhich the outer free end of the pivoted bar is adapted to strike as thedrill descends, and means for holding said rotatable wheel againstvertical movementas the drill is being raised, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN J. KOGER.
